I am wanting to update this with the latest bios, and with xbmc. The problem is I don't have a clue where or how to start. I recently saw a cool Youtube video of someone running xbmc and you could access all your Xbox game backups, emulators, and more, plus all the games had clean cover art etc... It was just a really nice setup. Here is a link to the video for how I would like mine to look/work when I'm done:

I also came across another video with some pretty cool hardware mods but it didn't have any info on how to do them. Here is a link for that video:

If anyone can help point me in the right direction I would be eternally grateful. I apologize if I posted this in the wrong forum I figured Evox because I am technically trying to upgrade. Thanks in advance for any help.

Grab HeXEn (Google Heimdall's Xbox Engineering Disc). Burn to DVD-R at 4x or slower. Use it to flash a newer BIOS (Option 3.2), then use option 3.5.2. Clean C partition after TSOP flash, then select option 4.1. Install XBMC to E. Use FTP to delete the current XBMC installation from E:\Apps\XBMC and replace it with the latest version. Reboot and make sure that XBMC works when you run it as an application from the dashboard.

Once XBMC works as an application you can use the dashboard switching tool (either run from the default UnleashX dash or from HeXEn - Option 5.1.4.3 Switch to XBMC on E) to change the default dash to XBMC.
